Exposure Device Operator Certification

NRCan NDTCB Service fees update

The NRCan NDTCB is implementing a service fees update to existing fees; this update will take effect April 1, 2023. Application and fee submissions to the NRCan NDTCB that are postmarked, emailed or faxed after March 31, 2023 are subject to the new fee schedule.

To perform gamma radiography or operate an exposure device in Canada, by law you must either:

  • Hold a valid exposure device operator (EDO) certificate from the Canadian Nuclear Safety Commission (CNSC), or
  • Be working under the direct supervision of a certified EDO (CEDO)

Our role in EDO certification

The Canadian Nuclear Safety Commission (CNSC) is responsible for certifying exposure device operators. The Natural Resources Canada Non-Destructive Testing Certification Body (NDTCB) serves as the qualifying body for CNSC's written examination for EDO certification.

If you are successful on the EDO written examination, and upon obtaining EDO certification from the CNSC, a photo ID card will be issued from the NRCan NDTCB and a separate certification card will be issued by CNSC with matching expiration timelines.

For questions about EDO certification beyond the written examination stage, please contact CNSC.
